Son accused of torturing father with makeshift blowtorch

A MAN allegedly tortured his elderly Maryborough father, holding him captive for days and burning his face with a makeshift blowtorch.

According to police documents, the 43-year-old man allegedly held his 74-year-old father against his will in Maryborough from June 14 to 17.

It was alleged the father, who has emphysema and requires continuous oxygen therapy, was not allowed to leave his lounge chair and had burns to his face from an aerosol used as an improvised blowtorch.

He also suffered injuries from allegedly being punched and from a "Chinese burn" - the action of twisting the skin of a person's arm in different directions simultaneously.

The father was finally able to alert police on June 17 after locking his son out of the house, according to the documents.

The alleged torturer is charged with three counts of assault, one of assault while armed, torture and possessing dangerous drugs.

He is in a Brisbane prison and did not appear in Maryborough court when his charges were mentioned on Monday.
